An explosive gas leak Tuesday at the Northern Alberta Institute of Technology has been contained.

Crews from Edmonton Fire and Rescue Services rushed to the post-secondary institution's Productivity and Innovation Centre after laboratory staff activated a fire alarm at 4:15 p.m. due to an ethylene gas leak from a cylinder.

The building was evacuated and deemed safe at 4:47 p.m.

Fire personnel closed the cylinder. Two crews then remained on scene ventilating the area. No injuries were reported.

NAIT confirmed to CTV News Edmonton that the leak came as a result of a component failure with the cylinder. The institution will, as a matter of protocol, conduct a post-incident review of the emergency.
